A new, high sensitivity laser vibrometer

Baker, J.R., Halliwell, N.A., Laming, R.I. and Wilmshurst, T.H. (1990) A new, high sensitivity laser vibrometer Optics & Laser Technology, 22, (4), pp. 241-244. (doi:10.1016/0030-3992(90)90054-8).

Record type: Article


This paper introduces a new design of laser vibrometer which allows high sensitivity, noncontact measurement of normal-to-surface target motion. The design includes use of a retro-reflective tape covered PZT-element to remove the sign ambiguity in surface velocity, which is inherent in the form of Doppler detection used in laser vibrometers. Utilization of this element offers the potential for a compact, cost effective design, suitable for portable, on-site use in engineering situations.
